When Penske/Jasper did my rebuild they told me not to use the old pulley they couldn't guarantee that it was good to use. I found a new/old still in the box pulley that the numbers match for my application (or I think so anyway) I just need your input. Thanks Pat

Like Clifford just mentioned. It's nice to see you posting. Your blog is bookmarked in all of my computers. If you have a chance keep us up to date.. Heck of a project that you have. We wish you the Best and moral support.

Ok, lets do this like this. When Penske/Jasper did my rebuild they told me not to use the existing pulley I supplied with the engine. I found a pulley/dampner on Ebay that according to the supplied numbers is for a 92 series DD. I noticed the dampner was missing from the ad. So I emailed the seller and he said that was an accident caused by one of his employee's and apologized for the error.

My question is what should I look at when deciding whether a pulley is usable or not? Penske/Jasper said the supplied pulley was pitted and not considered reliable. Which is fine with me. I'll just find a new one. Which it seems is the one I've located on ebay. I just wanted some input one the pro's or con's of pulley science.

Pat,that pulley looks like a 6v92 pulley notice the sealing area I don't know that would work on a 8v92 with a harmonic balance all I have here bolt to the hub of the harmonic balance is the harmonic balance on your engine

Look at it you will see it has 8 bolts holes and 2 dowels on a hub with a center bolts with cones behind it to tighten and align the harmonic balance you think the pulley is costly price the harmonic balance for a 8v92 from DD I don't see any way to attach the harmonic balance to that pulley

I guess Jasper replaced the harmonic balance they should have you never use a old one on s fresh rebuild on a 8v92

I checked my books that type pulley for a 8v92 does have the 10 bolts not 5 shown on the one you are looking at on Ebay

Thanks Clifford, yes the dampner is new from Jasper and I see the differences. Is there somewhere I can send this pulley to have to have it checked out/repaired or balanced?

I appreciate the input its tough beating experience. That pulley is the last major object on the engine. There are plently of sensors to install, the air throttle is looking good, I had to replace the tubing that I installed correctly (wrong size). I'm plugging away. I laid the tile in the Kitchen/bathroom area's, I still have the shower to do. It's nice having energy again......and I thought I was just losing interest.
